do morphological erosion of pixels based on neighbor counts
Syntax
ebsd = erode(ebsd,0)
ebsd = erode(ebsd,2,'titanium')
ebsd = erode(ebsd,1,{'a' 'b' 'notIndexed'})
Input
ebsd | EBSD |
counts | upper threshold of same phase pixels around each pixel to permit erosion |
phase | phase name, cell or string |
Output
ebsd | EBSD without the eroded pixels |
Example
mtexdata small
plot(ebsd); hold on
plot(ebsd('n'),'FaceColor','k'); hold off;
mtexTitle('original'); nextAxis
ebsd = EBSD (y↑→x)
Phase Orientations Mineral Color Symmetry Crystal reference frame

erode isolated, nonIndexed points
ebsd = erode(ebsd,0);
plot(ebsd); hold on

mtexTitle('no n,D,E \(\le\) 1 neighbors, 10 iter'); nextAxis
